SWITCH FOR OVERHEAD RAILWAYS FOR DRESSED MEATS.

SPECIFICATION forming part of Letters Patent No. 445,060, dated January 20, 1891.

Application filed September 22, 1890, Serial No. 365,813. (No model.)

To all (l/7107M it may concern:

Be it known that I, WALTER C. JARVIS, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improve ments in Switches for Overhead Railways for Dressed Meats, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in switches for overhead railways for use in the coolers in meat-packing houses, preferably; and it consists in the peculiar combination and arrangement of the same with the main and sub tracks, as will be fully specified hereinafter, and particularly pointed out in the claims.

My object is to provide a simple, cheap, and effective switch, allowingthe sheave carrying the meat to pass from the main to the sub track, and vice versa, without any danger of being derailed, as is very often the case with those now in use.

Referring to the drawings which illustrate the invention, Figure 1 is a plan view of a cooler, showing the construction of the main and sub tracks by means of my improved switches. Fig. 2 is a section of the same on a line as of Fig. 1. Fig. 3 is a perspective View of my invention, showing a different arrangement of tracks. Fig. -l is a detail view showing the switch detached from its pivotal connection with the track.

Similar letters refer to similar parts in all the figures.

A. represents a cooler, having ice-bow; 15 sit uatcd above the same in the usual manner. Doors and I) are situated at convenient places in the cooler for the entrance and exit of meats, the main track E entering at C and passing out at 1). Situated at suitable distances and in the same horizontal plane with the main track are subtracks F, which are, as is also the main track E, supported in position by hangers G, which, bolted at their upper ends to beams II of the cooler, depend and are bent under and secured to the several tracks, as will be readily understood. The sub-tracl-zs may be bent in any suitable direction desired, and are provided with pivotal switches I, which connect with the main track, as shown at J, or with sub-tracks K, as shown at L, these sub-tracks K being also provided with the pivotal switches M, which are in alignment with and when closed form practically a continuation of the main track E, as will be readily understood.

The meeting mitered ends N and O of the main. track E and sub-track switches M, respectively, are united as shown, and the ends P of switches I of sub-tracks E abut, when closed, against the main track in such manner that the outermitered orbeveled edgeN is in alignment with the direction of the outer edges Q of the switches I, and thus when switches M of sub-tracks Kare raised directs the sheaves R, carrying the meat suspended from hooks S, from the main track E to the sub-tracks F, and vice versa, as will be readily understood.

The hangers T are provided with the horizontal projections, which extend under and assist in supporting the free ends of tracks and sub-tracks at the several junctions, and are arranged in such manner that the passage of the sheaves along the track is not affected.

The construction of the several switches is as follows: The tracks are spliced at S, the rear ends of said splices extending downwardly and rearwardly, and the front end downwardly and forwardly, the decreased end T of the track and L" of the switch being pivoted together at V, the rear inclined end of switch being adapted when closed to bear againstthe under side of the downwardly and rearwardly extendingshoulderX of each track, and the forward end of each switch being provided. with the downwardly and forwardly inclined shoulder 'Y, which, when closed, bears upon the upper surface of the inclined end Z of the traclgas will be readily understood.

The shoulders of track and switch are out to form a notch orgrooveiu plan view, and the meeting ends of switch and track are V- pointed or sharpened to engage the said notch or grooves, thus affording additional strength in case of lateral strain.

In operation the meats are carried on main track E to cooler, the doors of which, made double-acting, without latches, and provided with notches c and (Z between them for the passage of the main track, are adapted when the meats are forced against thein to automatically open, and after the meat is in the cooler to close, thus affording entrance to but little outside air. To place the meat on the further sub-track, the switches of the intervening sub-tracks are thrown open by hand as the meat approaches, which when it reaches the said track passes upon it, as shown at A, Fig. 1. \Vhen ready to remove from the cooler, the meat is forced toward the exit-door D, and as it reaches the junction of the main track and switch I of sub-track the switch of sub-track K is operated, allowing the meat to pass upon the main track and through the exit-door to the car to be loaded.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-- I 1. The combination of a track having a decreased end forming a lateral shoulder extendingdownwardly and rearwardly, andhaving a forward decreased end inclined forwaraiy and downwardly, with a switch having a decreased portion provided'with an inn clined shoulder and end, which are adapted.-

when the switch is closed, to engage upon and under the end and shoulder of the track, substantially as described.

2. The combination, with a track having a downwardly and forwardly inclined decreased end forming a lateral shoulder, the said shoulder havinga groove therein, of a switch having a decreased portion provided with an inclined shoulder and inclined beveled end, which are adapted to engage upon and under the end and grooved shoulder of the track, as described. I

In testimony whereof I aflix my signature in presence of two witnesses.
